Question

If selling price is doubled, the profit triples. Find the profit percent ?
A) 100%
B) 200%
C) 300%
D) 400%

Answer 1

Answer:  

A) 100% 

Explanation:

Let the C.P be Rs.100 and S.P be Rs.x, Then 
The profit is (x-100)
Now the S.P is doubled, then the new S.P is 2x
New profit is (2x-100)
Now as per the given condition; 
=> 3(x-100) = 2x-100
By solving, we get 
x = 200
Then the Profit percent = (200-100)/100 = 100
Hence the profit percentage is 100%
